Paracetamol and Ibuprofen, hot water bottle, lots of sleep and water to keep you hydrated (can’t forget the chocolate of course!) And let those around you know you just feel a bit rough right now and might be a little snappier.
If the pain ever gets to the point where you are having to take several days off sick from school/work I’d go see your GP surgery and let them know it’s severe pain.
I was placed on a specific anti-inflammatory that really helped when I was younger, but now I’m on the pill, sounds scary and I put it off for years but it has significantly improved my quality of life and I don’t plan on staying on it forever, but its nice to not be in that much pain every month.
